RARE HETEROMORPH AMMONITE FOSSIL – CERATITES NODOSUS – MIDDLE TRIASSIC – HELLERBURG, GERMANY

This is an authentic and well-preserved fossil specimen of the classic ceratitid ammonite species Ceratites nodosus, originating from Hellerburg, Germany, and dating back to the Middle Triassic period, approximately 240 million years ago. It is part of the prestigious Alice Purnell Collection and has been carefully selected for its quality and scientific value.

You will receive the exact specimen pictured, with a 1 cm scale cube shown for accurate sizing. For full measurements, please refer to the provided photo.

All of our Fossils are 100% Genuine Specimens and come with a Certificate of Authenticity.

FOSSIL IDENTIFICATION

  • Species: Ceratites nodosus
  • Type: Heteromorph ammonite (though often referred to as “ceratites” to distinguish from later ammonoids)
  • Family: Ceratitidae
  • Superfamily: Ceratitoidea
  • Order: Ceratitida
  • Class: Cephalopoda
  • Phylum: Mollusca
  • Age: Middle Triassic (~240 Ma)
  • Stratigraphy: Likely from the Muschelkalk Formation, part of the Germanic Triassic Supergroup
  • Locality: Hellerburg, Germany

GEOLOGICAL & PALEOECOLOGICAL CONTEXT

Ceratites nodosus lived during the Middle Triassic, in the aftermath of the Permian-Triassic extinction—Earth’s most severe mass extinction event. Its fossil remains are commonly found in the Muschelkalk, a widespread marine limestone unit deposited in a shallow inland sea that once covered large parts of Central Europe.

  • Geological Stage: Anisian to Ladinian (Middle Triassic)
  • Depositional Environment: Shallow marine carbonate platform – a warm, tropical epicontinental sea environment ideal for ammonoid diversity
  • Biozone Association: Often found in association with other ceratitid fauna, such as Ceratites compressus and Ceratites semipartitus

MORPHOLOGY & FEATURES

  • Ceratites nodosus is easily recognised by its broad, involute shell and the presence of strong nodose ornamentation (rounded tubercles or “nodes”) along the flanks.
  • It has partially frilled ceratitic sutures—a distinctive trait of the Ceratitida order—where lobes are frilled but saddles remain smooth.
  • This species provides key insight into the early re-diversification of ammonoids after the end-Permian extinction and represents an important evolutionary step in cephalopod history.

NOTES & SIGNIFICANCE

  • Ceratites nodosus is an index fossil for the Middle Triassic in Central Europe, making it valuable for stratigraphic correlation.
  • This species has been formally described and extensively studied since the 19th century, especially within German palaeontology.
  • Hellerburg is a classic fossil site and has yielded exceptional specimens over the years.

ITEM SUMMARY:

  • Rare Ceratites nodosus ammonite fossil
  • Middle Triassic (~240 million years old)
  • From Hellerburg, Germany
  • Member of the renowned Alice Purnell Collection
  • Supplied with Certificate of Authenticity
  • Exact fossil shown in listing photographs
  • 1 cm cube in image for scale reference

A beautifully preserved example of a historically significant Triassic ammonite. Ideal for collectors, educators, and palaeontology enthusiasts seeking a genuine piece from one of the most crucial periods in evolutionary history.

Triassic Information

The Triassic Period (252–201 million years ago) marked the beginning of the Mesozoic Era, following the Permian-Triassic mass extinction, the most severe extinction event in Earth's history. The climate was hot and dry, with vast deserts and little polar ice. Life slowly recovered, leading to the rise of the first dinosaurs, pterosaurs (flying reptiles), and early mammals. Reptiles, including large archosaurs (ancestors of crocodiles and dinosaurs), dominated both land and sea. In the oceans, ichthyosaurs and plesiosaurs thrived alongside ammonites and early coral reefs. The first true conifers and ginkgo trees spread across the land. The period ended with another mass extinction, paving the way for the Jurassic and the golden age of dinosaurs.
